The most secure type of encryption devised to date is Quantum Key Distribution. It keeps data secure by sending series of entangled photons via aquantum network to receivers that allow, by detecting the polarization of these photons, the creation of a key for deciphering a message that has been sent via a conventional data link. The security is based on a fundamental quantum mechanical property: Any action taken to detect the quantum state of the photons as they make their way to the receiver will change their quantum states, which will be noticed by the users. ….
